Description

Technical Field

[0001] The invention relates to the technical field of cutting machines, in particular to a round-to-round die-cutting structure. Background Art

[0002] A rotary die-cutter is a cutting machine that is often used in mass production. With the advancement of technology, printing technology has gradually improved. While the efficiency and effect of printing technology have improved, some of the printed products are integrated and need to be separated by cutting. Previously, they were separated by manpower, which was slow and effective, resulting in different sizes of separated products. In order to cope with this situation, people have designed a rotary die-cutter that sends the cardboard between the embossing plate roller and the pressure roller, which clamps it and performs die-cutting on the roller. One rotation of the die-cutting plate roller is a working cycle.

[0003] However, the die-cutting blades inside the existing rotary die-cutting machines are mostly installed at the upper end of the paper. The paper is pulled into contact with the die-cutting blades and separation is completed. This separation method will make it difficult for the cutting knife to cut thoroughly, resulting in abnormal separation. Therefore, it does not meet the existing needs. In this regard, we propose a rotary die-cutting structure. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention is provided with a lower roller at the lower end of the upper roller, and a die-cutting blade is provided on the outside of the lower roller. When the external paper is transported into the device, the paper can be pulled and moved downward by its own gravity. The downward movement of the paper can be coordinated with the position of the die-cutting blade, so that the paper can pass through the die-cutting blade. Passing through the die-cutting blade can improve the cutting effect of the device on the whole paper and avoid abnormal separation. On the other hand, when the paper is cut by contacting the die-cutting blade on the outside of the lower roller, the precision requirement of the die-cutting device can be reduced, the manufacturing difficulty and maintenance difficulty of the tool are reduced, the service life of the tool is increased, the economic benefit of the device is greatly improved, and the manufacturing cost is reduced.

[0015] 2. The present invention is provided with an upper clamping roller on one side of the receiving paperboard, a lower clamping roller is provided at the lower end of the upper clamping roller, and a waste cleaning shovel is provided at the lower end of one side of the lower clamping roller. Waste will be generated after the paper is cut by the die-cutting blade. When the waste moves between the upper clamping roller and the lower clamping roller, the upper clamping roller and the lower clamping roller clamp the paper and the waste. During clamping, the hook will hook the waste and separate the waste through the waste cleaning shovel. The waste is uniformly handled and uniformly piled up at a certain position, which is convenient for the staff to handle the waste and also prevents the waste from being scattered randomly and causing a poor working environment.

[0016] 3. The present invention is provided with a first transmission gear on one side of the upper clamping roller, a support shaft is provided at the lower end of the first transmission gear, and a plurality of second transmission gears are evenly provided in an outer ring of the support shaft. Different cutting objects are different. In order to adapt and improve the adaptation effect of the ingredients, the extension and retraction of the first support frame can push the distance between the upper clamping roller and the lower clamping roller. When adjusting the distance, the extension and retraction of the first telescopic rod can push the second transmission gear to squeeze the transmission belt. After the transmission belt is squeezed, the distance between the first transmission gear and the second transmission gear can be reduced, so that the upper clamping roller and the lower clamping roller can still rotate at the same time when the distance is adjusted. On the other hand, upper synchronization device shells are provided on both sides of the outside of the device support frame. The rotation of the upper synchronization device shell can make the device support frame as a whole longitudinally adjust the height, so that the device can adapt to different installation positions and usage requirements.

The protection of the upper shielding cover 28 and the lower shielding cover 29 can prevent external foreign matter from entering the interior of the device, thereby improving the service life of the device.

[0031] Furthermore, transmission threaded rods 12 are provided at the four corners of the outside of the device support frame 1, and the transmission threaded rods 12 are threadedly matched with the transmission threaded rods 12, a thickness adjustment block 11 is provided at the upper end of the transmission threaded rod 12, and the thickness adjustment block 11 is fixedly connected to the upper end of the transmission threaded rod 12, a height adjustment block 2 is provided at the lower end of the transmission threaded rod 12, and the height adjustment block 2 is fixedly connected to the transmission threaded rod 12, a non-slip pad 26 is provided at the lower end of the height adjustment block 2, and the non-slip pad 26 is fixedly connected to the height adjustment block 2, a rotating handle 31 is provided on one side of the upper end of the thickness adjustment block 11, and the rotating handle 31 is fixedly connected to the thickness adjustment block 11, the rotation of the transmission threaded rod 12 causes relative movement between the device support frame 1 and the transmission threaded rod 12, and the device support frame 1 is converted from rotational motion into linear motion, thereby adjusting the overall height of the device.

[0032] Furthermore, a first support frame 15 is arranged between the paper receiving paper 10 and the device support frame 1, and the first support frame 15 is fixedly connected to the paper receiving paper 10 and the device support frame 1, the lower clamping roller 21 and the upper clamping roller 24 are rotatably connected to the device support frame 1, and a second support frame 27 is arranged outside the paper receiving paper 10, and the second support frame 27 is fixedly connected to the device support frame 1, and the support of the paper receiving paper 10 can effectively assist the transportation of paper and waste.

[0033] Working principle: when in use, in order to improve the cutting effect of the device on paper, when the paper is transported into the device, the lower clamping roller 21 and the upper clamping roller 24 clamp the paper and cooperate with the gravity of the paper, the paper will fit with the die-cutting blade 9 outside the lower roller 8 and complete the cutting, preventing the die-cutting blade 9 from not completely passing through the paper, avoiding normal separation. In order to improve the convenience of waste disposal after paper cutting, the cut paper and waste are clamped by the lower clamping roller 21 and the upper clamping roller 24. During clamping, the waste will contact the hook 23, and the hook 23 contacts the ingredients and restricts the waste. The restricted waste rotates with the rotation of the lower clamping roller 21, and the waste cleaning shovel 3 fits with the hook 23 and removes the waste on the surface of the hook 23, so as to facilitate the unified accumulation and disposal of the waste. The distance between the cylinder 21 and the upper clamping roller 24 can be adapted to papers of different thicknesses. The extension and retraction of the second telescopic rod 25 can drive the upper clamping roller 24 to adjust its height longitudinally. When the height of the upper clamping roller 24 is adjusted, the extension and retraction of the first telescopic rod 18 can push the second transmission gear 19, and adjust the distance between the first transmission gear 16 and the second transmission gear 19 by adjusting the length of the transmission belt 20, so that after the height position of the upper clamping roller 24 is adjusted, it can still be rotated simultaneously through the transmission of the transmission belt 20. On the other hand, the rotation of the rotating handle 31 can drive the transmission threaded rod 12 to rotate through the thickness adjustment block 11. The rotation of the transmission threaded rod 12 causes relative movement between the device support frame 1 and the transmission threaded rod 12, and converts the device support frame 1 from rotational motion to linear motion, thereby adjusting the overall height of the device.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
